Meteorite Type:	H3 Chondrite (estimated 3.6)

 
Macroscopic Description: Kathleen McBride
The exterior of this ordinary chondrite is covered completely with smooth, shiny fusion crust, exhibiting numerous oxidation halos. The interior is mostly rust with abundant metal. There are mm-sized chondrules that are stained with rust and appear as small specks. This meteorite is very hard.

Thin Section (,2) Description: Tim McCoy
The section exhibits numerous well-defined chondrules (most ~0.5 mm in diameter), metal and troilite. Weak shock effects are present. Polysynthetically twinned pyroxene is abundant. Weathering is pervasive, with extensive staining. Silicates are unequilibrated; olivines range from Fa_9-23 and pyroxenes from Fs_1-25. The meteorite is probably an H chondrite of subtype ~3.6.

Macroscopic Description: Kathleen McBride
The exterior of this carbonaceous chondrite has brown/black shiny fusion crust covering 100% of its surface area. It is fractured and has oxidation halos. The interior has a dark matrix with some rust and metal. Irregularly shaped chondrules are light colored, stained with rust. Other inclusions appear rusty, tan and gray in color.

Thin Section (,2) Description: Tim McCoy
The section exhibits large chondrules (up to 3 mm) and CAIs in a dark matrix. Olivines range from Fa_1-31, with most Fa_1-5, and pyroxenes from Fs_1-2. The meteorite is an unequilibrated carbonaceous chondrite, probably a CV3.

Macroscopic Description: Kathleen McBride
This aubrite is extremely altered and is very rusty inside and out. It has small thin patches of fusion crust that comprise less than 5% of the surface area. It is very friable and crumbles easily. QUE97348 contains mm-sized inclusions.

The section consists of mm-sized enstatite grains (Fs_0.1), reasonably abundant (10% or more?) feldspar of variable composition (An_4-35), Si-bearing metal (1.9 wt.% Si), Ti-bearing troilite, daubreelite, alabandite and schreibersite. The latter phases often occur as rounded enclaves in the enstatite. The meteorite is an unusual aubrite. It is similar in many respects to LEW 88055 (Casanova et al., 1993, LPSC XXIV, 259-260).

Meteorite Type:	H5 Chondrite

Macroscopic Description: Kathleen McBride
100% of this ordinary chondrite’s exterior has rough, black fusion crust with oxidation halos. The interior is a steel gray color with rusty patches and is somewhat flaky. It is very dense with no visible inclusions.

Thin Section (,2) Description: Tim McCoy
This meteorite is a strongly shocked H5 chondrite (Fa₂₀,Fs₁₇) with shock blackening and dispersion of metal and troilite. Olivines exhibit planar fractures and mosaicism.

Macroscopic Description: Kathleen McBride
The exterior of this carbonaceous chondrite is dull and black with white evaporites along the edges. The top face has a large yellowish brown inclusion. The meteorite appears to have no fusion crust. The interior is brown, very weathered and crumbles easily. Evaporite deposits are present on the interior surface.

Thin Section (,6) Description: Tim McCoy
The section consists of a few small chondrules (up to 0.5 mm), mineral grains and CAIs set in a black matrix; rare metal and sulfide grains are present. Olivine compositions are Fa_0-4, orthopyroxene is Fs_1-2. The matrix consists dominantly of an Fe-rich serpentine. The meteorite is a C2 chondrite.

Macroscopic Description: Kathleen McBride
40% of the exterior of this achondrite is covered by thin, shiny black fusion crust. Exposed interior is medium gray in color with white and tan inclusions. The interior is a gray matrix with tan and white clasts, 1 to 4 mm in diameter. This meteorite is coherent and moderately hard.

Thin Section (,6) Description: Tim McCoy
The section consists dominantly of a mixture of mm-sized orthopyroxene (Fs₆₀Wo₃), with lamellae of augite (Fs₃₀Wo₄₂), and plagioclase (An₉₀Or_0.5). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is brecciated and severely shocked. The meteorite is a eucrite.

Macroscopic Description: Kathleen McBride
80% of the surface of this achondrite is covered with black fusion crust with shiny patches. There are several large (0.5-2.0 cm) "vugs" where sample material has weathered or has been plucked. The interior has a sugary texture, with a grayish green matrix. Black grains and some clasts are interspersed throughout the matrix. Pure white inclusions, rusty halos and streaks are visible. Several white clasts with matrix material incorporated into the clast are present.

Thin Section (,6) Description: Tim McCoy
The section consists dominantly of a mixture of mm-sized orthopyroxene (Fs₆₄Wo₂), with lamellae of augite (Fs₂₈Wo₄₄), and plagioclase (An₈₈Or_0.5). The Fe/Mn ratio of the pyroxene is ~30. The meteorite is a brecciated eucrite.

Macroscopic Description: Katlheen McBride
The exterior of this meteorite is coarse grained and crystalline with white linear, criss-crossing veins of sugary textured material. The matrix consists of reddish-brown crystals, milky white feldspar crystals, some euhedral and gray translucent crystals. Some thin black patches of shiny fusion crust are present (about 10%). The interior is similar to the exterior except the interior veins are more yellowish in color.

Thin Section (,18) Description: Tim McCoy

,16 - Silica Grain	,18 - Normal Part	,18 - White "vein"	,18 - Fusion Crust

The section consists dominantly of a mixture of mm-sized orthopyroxene (Fs₅₉Wo₅), with 1-5 micron lamellae of augite (Fs₃₅Wo₃₃), and plagioclase (An₈₉Or_0.5). The Fe/Mn ratio of the pyroxene is ~31. A sub-equal mixture of plagioclase and SiO₂ with minor pyroxene dominates the white veins seen in hand sample. The dominant opaques are Fe, Ti-and Fe,Ti,Cr,Al-oxides with minor iron sulfide and rare iron metal. The meteorite is a eucrite.
